Description

[Detailed Description of the Invention] <Technical Field of the Invention> The present invention displays various keys as symbols on the screen of a display device, and by appropriately indicating the key symbols displayed on the screen, key input of information is performed. This article relates to a new word processor that can perform the following tasks.

<Prior art> Most conventional word processors are equipped with a keyboard,
The keyboard is configured to input various information. This type of keyboard has a large number of keys, such as numbers, symbol keys, alphabet keys, kana keys, and keys for specifying upper and lower case letters, as well as cursor keys, non-conversion keys, conversion/candidate keys, line feed keys, dictionary keys, and edit keys. Because the keys are arranged in such a way that the operator does not know where each key is located, it is difficult for the operator to perform key operations quickly. Furthermore, the presence of a keyboard increases the size of the device and increases the cost.

<Object of the Invention> The present invention has been made in view of the above-mentioned problems of the conventional art. A display device for displaying text is provided with a symbol display area for each key, and the key symbols displayed on this screen are displayed. By making it possible to input a variety of information by giving instructions, and by configuring it so that when an input mode is specified using the display key, the key symbol related to that specified mode is automatically switched and displayed. It is an object of the present invention to provide a word processor which is miniaturized, has a reduced number of keys, and has significantly improved key operability.

<Example> The present invention will be explained in detail below based on the drawings.

This tablet is placed on the back side of the liquid crystal display device 1 and is configured to detect the magnetic lines of force generated by a stylus pen operated on the display screen to detect the position of the pen. 7 is an asynchronous data transfer interface for converting the coordinate data serially output from the tablet 6 into parallel data and combining it with the pass line 8; 9 is a read-only memory (ROM) for storing system control programs and character patterns;
l), 10 is a read-only memory (RO) that stores application programs and character recognition control programs in advance.
M2), 11 is a system control memory, and 12 is a program group memory.

Still, 13 is a central processing unit that performs the main control of this system, 14 is a buzzer used for warning in case of erroneous operation, etc.
15 is a key input device equipped with keys other than the keys on the screen which will be described later; 16 is an interface with a clock circuit 17;
10 address decoders, memory chip selects, interrupt control circuits, power supply control circuits, and other control signal generation circuits are integrated into one, and is composed of a gate array. 18 is an interface circuit with an external communication interface, 19 is a power supply circuit, 20 is a connector for connecting an external keyboard, 21 is a connector for connecting an external device to the system path 8, 22 is a connector for connecting an AC adapter, and 23 is a connector for connecting an external device to the system path 8. This is a connector with an external communication interface.

FIG. 2 shows an example of display by the liquid crystal display device 1 described above.

24 in the figure is a text display area, and in this area, two
It is designed to display the same amount of text as would be written on a 200-character manuscript sheet of 0 characters x 10 lines. 25 is a line number display area that displays the line number of the text.
- When the gender characters (maximum 40 characters) are displayed over two lines, this happens when a line break exceeds 20 characters, but this can be clearly recognized. The width of the delimiter that separates the line numbers of the relevant part (in this example, the 5th, 6th, and 7th lines) can be displayed wider than other parts.

26 is an area for displaying key symbols for switching input modes such as hiragana or katakana input mode using romaji, alphabet input mode, numeric symbol input mode, uppercase and lowercase input mode; for example, "romaji" and "kana". When you touch a key symbol with the stylus pen, that part becomes a black and white inverted pattern from the other parts, making it easy to recognize at a glance that you are in Roman hiragana input mode. In this case, hiragana can be input using the vowel key of "AIUEO", the consonant key of rKsTNHMYRWJ, the dakuon key of "'", and the semi-dakuon key of "." displayed in the area 27. Each time the input mode changes, the key symbols displayed in this area 27 are switched to key symbols related to that mode. 28 is an area that displays the symbols of each function key such as the conversion/candidate key, line feed key, edit key, etc. 29 is an area that displays some candidate kanji when converting from kana to kanji. By touching any one of the candidates with the stylus pen, that kanji can be input at the cursor position in the text display area 24.

FIG. 3 is a flowchart showing the control operation when each symbol p of the input mode switching keys displayed in the display area 26 is designated with a stylus pen.

First, in the normal mode, areas 26 to 26 on the screen of the display device 1
At 28, a key symbol as shown in FIG. 2 is displayed (nl). Next, it is determined which key symbol on the screen is specified with the stylus pen (n2.n3 to n1).
0). Now, when the "alphabet" key symbol is specified, set the flag FA indicating alphabet input mode (n1l), FR, FHK, FKK, FKI.
, and reset each flag of FKO (n12)
, key symbols related to the alphabet input mode are displayed in area 27 on the screen (n1B). FIG. 4 shows an example of the display at that time, and FIG. 5 shows an example of the display when a "small" symbol is specified next to the symbol, and in this case, lowercase letters can be input.

Similarly, when the "kana" and "kana j" symbols are touched with the stylus pen, steps n14 to n are performed, respectively.
16+Proceed to steps n17 to n19, and the screens shown in FIGS. 6 and 7 are displayed in the area 27 on the screen according to each input mode.
Display key symbols as shown in the figure. However, the 6th
7 are display examples when inputting lowercase letters.

Also, when the "Romaji" symbol is specified, since the flag FHK has already been set (n20), the flag FR indicating the Romaji input mode is set, and FA,
After resetting both flags of FKI (n22), display the key symbol shown in Figure 8 in area 27 on the screen (
n2B). That is, in the Roman character input mode, either the kana input mode (see FIG. 2) or the kana input mode (see FIG. 8) can be set.

Furthermore, when the "small" symbol is specified with and -, the flag FKO indicating the lowercase letter input mode is set (n24).
), one of the key symbols shown in FIGS. 5 to 7 is displayed in the area 27 on both sides according to the state of each previous input mode flag (n25).

Furthermore, when the "symbol" symbol is specified, a flag FKI representing the symbol input mode is set, and a counter CKI representing the number of sides of the symbol input display screen in the area 27 is reset L (n27); 9th in area 27
The key symbol shown in the figure is displayed (n28). Now, if you specify the "next" symbol in this state, step n29.
Proceed to n30. That is, the counter CKI is incremented every time the "next" symbol is designated, and is reset to 0'' when the counter value exceeds a predetermined number n.Therefore, in the area 27, the "next" symbol is incremented. Each time a symbol is specified, four key symbols as shown in FIG. 10 (1) to (4) are repeatedly displayed.

Fig. 11 shows the processing flow in the custom character mode, and Fig. 12 shows an example of the display in the custom character mode. As shown in the external character setting section 30. A registration 31 and a designation section 32 are displayed. For example, if you input a heart shape into the external character setting section 30 using a stylus pen, that pattern will be displayed on the setting section 30 (n1=n in FIG. 11).
(see 5). Next, point to the "Register" symbol 31,
This external character is registered and displayed at a predetermined position in the designation section 32 (n6 to n8).

All the registered characters in this way are displayed in the designation area 32, so when you use the stylus pen to specify the symbol μ of a desired character from among the many characters currently displayed, that character will be displayed in the text display area. It is input and displayed at the cursor position in 24 (n9 to n1l).

FIG. 13 shows the operation flow in the common phrase mode, and FIG. 14 shows an example of its display. In this case, when you specify the symbol p for "common phrase" in the area 28 on the screen, the previously registered common phrase is displayed in the text display area 24 along with its initial letter - as shown in Figure 14. .

In addition, when registering a new item, use the key symbols in the area 27 to input, for example, the initial letter ``Ba'' and the common phrase ``Personal Computer'' in sequence, and the text will be displayed as shown in the figure in the text display area 24 and registered. I can do it.

Fig. 15 shows the operation flow in the edit mode, and Fig. 16 shows an example of its display.First, when you point the symbol "1 Edit" on the screen with the stylus pen, the area 27 shows the display shown in Fig. 16. Edit commands are displayed. For example, ``
When you specify the symbol "Enter code", the same display area 2
7, a code input section as shown in FIG. 17 is displayed in place of the previous display. Therefore, you can use this to immediately input a conid.

FIG. 18 shows the operation flow in layout mode, and FIG. 19 shows an example of its display. "" displayed in the display area 28
When the "Layout" symbol is designated, the paper-outside print layout is displayed in a window in area 33 of text display area 24, as shown in FIG. By instructing the "layout" symbol again, the layout display can be erased and the normal display can be restored.

In this way, the word processor of the embodiment displays the key symbols necessary for creating and editing texts on the text display device, and inputs information by pointing the key symbols with the stylus pen. Therefore, the conventionally required keyboard can be omitted. Therefore, it is possible to reduce the size and cost of the device. Furthermore, when you specify any of the key symbols p displayed on the screen, various key symbols related to that key symbol are displayed in a predetermined area 27 on the screen.
A desired key symbol can be easily found, and erroneous inputs can also be reduced.

In the above embodiment, information is input using a tablet and a stylus pen, but as explained in detail above, the word processor of the present invention allows for miniaturization of the device. In addition to reducing costs, key operability can be significantly improved.
